This slurry cannot be dewatered on plaster since the gum will seal the pores and possibly ruin it. So I used an Arborite surface. This amount of liquid would take a week to air-dry but under a fan, it took about 8 hours (the process is slow because of the high water content coupled with the gum content). When dry it scraped it off with much difficulty because it set so hard. I then ball-milled the dried material to powderize it, producing enough non-plastic material to making SHAB test bars.

DIY Underglaze Development
I studied a range of underglazes to understand what they are. Instead, I found out what they should be and how DIY is the key to tuning the degree of fired maturity for my temperature, minimizing costs and tuning the working properties. |
